Akashi Kaikyō Bridge The bridge has three  spans . The central span is 1,991 m (6,532 ft; 1.237 mi),and the two other sections are each 960 m (3,150 ft; 0.60 mi). The bridge is 3,911 m (12,831 ft; 2.430 mi) long overall.  The two towers were originally 1,990 m (6,530 ft; 1.24 mi) apart, but the  Great Hanshin earthquake  on January 17, 1995, moved the towers so much (only the towers had been erected at the time) that the span had to be increased by 1 m (3.3 ft). The bridge was designed with a two hinged stiffening girder system, allowing the structure to withstand winds of 286 kilometres per hour (178 mph), earthquakes measuring up to magnitude 8.5, and harsh sea currents. The bridge also contains  tuned mass dampers  that are designed to operate at the  resonance frequency  of the bridge to dampen forces.  The two main supporting towers rise 282.8...

Longest bridge over water opens in China Longest bridge over water: The Jiaozhou Bay bridge is 26 miles long and links China's eastern port city of Qingdao to the island of Huangdao. CHINA OPENS THE WORLD'S LONGEST BRIDGE OVER WATER, TOPPLING AMERICAN RECORD-HOLDER Along with its massive  high-speed rail  network, China has officially surpassed the United States in yet another piece of transportation infrastructure: the world's longest sea bridge . The new bridge spans Jiaozhou Bay, on the southern coast of China's Shandong Peninsula in northeastern China. At 26.4 miles long, it beats Louisiana's Lake Pontchartrain Causeway — the previous world-record holder — by at least 2 miles, according to the  Guinness Book of World Records . Chinese workers toiled at marathon pace to build the bridge in four years, starting at each side and meeting in the middle. The structure has 5,200 pillars and cost at least...
